: [[Neutron Radiation|Neutron]] sources are kept inside a block of [[lead]] with a hole that only allows the '''[[neutron]]s''' out in one direction.
: [[Neutron Radiation|Neutron radiation]] is too dangerous to handle directly so it must be done from behind a thick [[lead]] screen.
: When handling a source of [[Beta ParticleNeutron Radiation|beta radiationNeutron]] the precautions which should be taken are::*Wear gloves - to prevent [[Radioactive Contamination|contaminationemission]].:*Use tongs to handle the source, never touch it - to prevent is usually stimulated by bombarding [[Radioactive ContaminationAtomic Nucleus|contaminationnuclei]] and reduce with other [[irradiationparticle]] (the tongs won't be long enough to prevent s. The [[irradiationNeutron Radiation|neutron]].):*Aim the source away from any living sources have a very short [[organismHalf Life|half life]] - so they do not need to prevent [[irradiation]].:*Store the source be kept in a sealed container - to prevent [[Radioactive Contamination|contaminationLead]] and containers for long before they are no longer dangerously [[irradiationradioactive]].
===Applications===
: [[Neutron]]s are used to stimulate [[Nuclear Fission|nuclear fission]] in both [[Nuclear Reactor|nuclear reactors]] and [[Nuclear Bomb|nuclear bombs]].
